Chrysanthemum plant named &#39;vamp time dark pink&#39;

ABSTRACT

A new variety of Chrysanthemum plant named ‘Vamp Time Dark Pink,’ having a good uniform canopy of dark pink decorative flowers. The new variety has a medium vigor, free branching, with a uniform spreading habit and good foliage presentation.

LATIN NAME OF THE GENUS AND SPECIES

[0001] Botanical classification: Dendranthema grandiflora.

VARIETY DENOMINATION

[0002] The new Chrysanthemum variety denomination is ‘Vamp Time Dark Pink.’

BACKGROUND OF THE INVENTION

[0003] The present invention comprises a new and distinct cultivar of Chrysanthemum botanically known as Dendranthema grandiflora, and referred to by the cultivar name ‘Vamp Time Dark Pink.’ ‘Vamp Time Dark Pink,’ identified as 20544-1, originated from a whole plant mutation grown in a controlled planting of the unpatented variety ‘Vamp Time,’ in Chichester, West Sussex, United Kingdom. The new variety ‘Vamp Time Dark Pink’ has been asexually reproduced by vegetative cuttings in Chichester, West Sussex, United Kingdom and the distinguishing characteristics are retained through successive generations of asexual reproduction.

BRIEF SUMMARY OF THE INVENTION

[0004] ‘Vamp Time Dark Pink’ is a pot type of Chrysanthemum plant variety having dark pink decorative flowers with a domed capitulum form.

Comparison with Parent

[0005] Plants of the new Chrysanthemum variety ‘Vamp Time Dark Pink’ are similar to the parent cultivar ‘Vamp Time’ in plant habitat and growth rate. In side-by-side comparisons in Chichester, West Sussex, United Kingdom, under commercial practice, plants of the new Chrysanthemum variety ‘Vamp Time Dark Pink’ compared to plants of the parent cultivar ‘Vamp Time’ in the following characteristics.

[0006] 1. The new variety ‘Vamp Time Dark Pink’ produces dark pink decorative flowers whereas the parent cultivar ‘Vamp Time’ produces light pink flowers.

[0007] 2. Plants of the new variety ‘Vamp Time Dark Pink’ have similar inflorescence to plants of the parent cultivar ‘Vamp Time.’

Comparison with Other Varieties

[0008] Plants of the new Chrysanthemum variety ‘Vamp Time Dark Pink’ are dissimilar to the cultivar ‘Padmos Time Pink’ (U.S. Plant patent application Ser. No. ______), in plant habitat and growth rate. However, in side-by-side comparisons in Chichester, West Sussex, United Kingdom, under commercial practice, plants of the new Chrysanthemum variety ‘Vamp Time Dark Pink’ compared to the plants of the cultivar ‘Padmos Time Pink’ in the following characteristics.

[0009] 1. The new variety ‘Vamp Time Dark Pink’ produces dark pink decorative flowers whereas the cultivar ‘Padmos Time Pink’ produces dark pink decorative flowers.

[0010] 2. Plants of the new variety ‘Vamp Time Dark Pink’ have larger and taller inflorescence than plants of the cultivar ‘Padmos Time Pink.’

BRIEF DESCRIPTION OF ILLUSTRATION

[0011] Typical specimens of the plant and flowers for the new Chrysanthemum variety ‘Vamp Time Dark Pink’ are shown in the accompanying digital photograph. The colors shown are as true as possible within the usual limits of this kind of illustration. FIG. 1 is a whole plant view of the new variety ‘Vamp Time Dark Pink’ grown in a pot. The plant shown in the illustration is 54 days from the commencement of Short Days.

DETAILED BOTANICAL DESCRIPTION

[0012] The following description of the new Chrysanthemum variety ‘Vamp Time Dark Pink’ is of plants grown in a greenhouse in Chichester, West Sussex, United Kingdom in the month of May. The cultivar has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in the environment such as temperature, length of day and light intensity, without any variance in genotype. The commercial classification of the new variety is a pot Chrysanthemum.

[0013] Plants of the new variety have been grown successfully under temperature conditions averaging about 19° C. at night and about 17° C. to 24° C. during the day under light conditions of about 5000 to 6000 foot candles. The plants respond well to the use of growth retardant, such as B9 treatment at about 2 g per litre. To produce a commercial product the plants may be pinched once with the center bud removed. The typical container size for commercial growth is 1 litre. It has been observed that the shelf life of the new variety is about 28 days with a response time of about 7.5 weeks. The new variety is suitable for growth in a temperature range of 15° C. to 25° C.

[0014] The new variety may be produced as a spray. The following description is with respect to a plant produced as pot. In the description of this new Chrysanthemum variety, color values have been taken from The Royal Horticultural Society Color Chart (R.H.S.C.C.).
